I want to zoom pictures in an epub file (e.g. screenshots in an oreilly.com e-book). Is it possible and if yes how? I haven't found anything in the manual and for some epubs it's essential to be able to zoom a picture.

I was surprised to find out it couldn't pinch to zoom on pictures in epubs as well.

I wasn't surprised exactly, but I was disappointed to find out it does not have this capability. My Sony T1 does this beautifully, and it is a highly useful feature, I've seen books that sometimes have TEXT PASSAGES done as images, and being able to zoom is sometimes the only thing that makes them readable!

I have a T1 too and I got it because it was the best thing out for reflow last year when I bought it. I guess I've gotten spoiled and assume everything can handle things as well as the T1. If only the T1 had a nice fronlit screen like at least the PW.
